自由粒子布朗运动的非马尔可夫效应

Non-Markovian Effects on the Brownian Motion of a Free Particle

A. O. Bolivar

摘要:

在Fokker-Planck方程(Rayleigh方程和Smoluchowski方程)的框架下,研究了在有和无惯性力作用下,自由粒子布朗运动的非马尔可夫效应.更具体地说,据预测,非马尔可夫特征可以提高均方位移和动量的值,从而确保这些物理可观测量的可微性的数学性质。

英文摘要:

Non-Markovian effects upon the Brownian movement of a free particle in the presence as well as in the absence of inertial force are investigated within the framework of Fokker-Planck equations (Rayleigh and Smoluchowski equations). More specifically, it is predicted that non-Markovian features can enhance the values of the mean square displacement and momentum, thereby assuring the mathematical property of differentiability of the these physically observable quantities.
